At 1:32 p.m. EST, the company's profile photos were changed to a Cadillac logo and advertisement.

The hackers also changed the account's description to read: "The official Twitter Handle for the Jeep - Just Empty Every Pocket, Sold To Cadillac =[ #OpMadCow #OpWhopper."

The background picture on the account was changed to a McDonald's-themed Cadillac.

Hackers then made a series posts to the account, starting with a tweet that said, "WELCOME BACK CADILLAC #300."

The unauthorized tweet, photos depicting drug usage and the Cadillac advertisement were removed from the site by 3 p.m. ET.

Jeep's Twitter was fully restored by about 5 p.m. ET.

"Hacking: Definitely not a #Jeep thing. We're back in the driver's seat!," a tweet on the Jeep site read.

Chrysler Group LLC, the parent company of Jeep, made a vague statement about the hack on their Twitter page.

"Thanks for all the heads up on one of our brand accounts. The team is on it. It's good so many of you have our back! ^MD"

"^MD" indicates the tweet was sent from Mike Driehorst, a spokesperson for Chrysler.

"With the help of Jeep fans, we knew about it immediately. At this point we don't know who did it, but we will work with Twitter to find out what happened," Chrysler spokeswoman Eileen Wunderlich told WTOL.

In an elaborate PR hoax, MTV and BET staged their own fake hack, switching the network's branding. BET's page featured an MTV icon and tweets like "We're bringng JERSEY SHORE BACK!!! #MTVhack." Jersey Shore ran for several seasons on MTV. MTV's page featured a BET logo.

Much like the Jeep Twitter account, the Burger King Twitter page had its profile pictures changed to advertisements of industry competitor McDonald's.

Many suspected that Monday's Burger King incident was caused by LulzSec, a division of the hacker group Anonymous. Anonymous hasn't claimed responsibility for the Jeep incident and the group's Twitter page inferred they have no involvement.
